-
Paragraph 0177-0180, (2019/01/10)
Disclosed are derivatives of 1H-imidazole-4,5-dicarboxamide and use thereof in preparation of anticoccidial drugs. The derivatives have structural formulae as shown in formulae (I) to (VI). The derivatives of 1H-imidazole-4,5-dicarboxamide as disclosed in the present invention have significant anticoccidial effect, especially against coccidia that show a resistance to other anticoccidial drugs, and thus they can be used in preparation of anticoccidial drug.

Phthalonitrile undergoes partial hydration in MeOH-H2O media in the presence of an equimolar amount of NaOH to afford 2-carbamimidoylbenzoic acid in good yield in one step. This and similar vic-amidino (hetero)aromatic acids also could be synthesized from corresponding 1,2-dinitriles by hydrolysis in aqueous MeOH catalyzed by an equimolar amount of NaOH of in situ generated 1,1-dimethoxy-1H-isoindol-3-amine or its counterparts. Protonation of the synthesized amidino acids, esterification, and reamination of the parent amidino benzoic acid with N-nucleophiles were performed.
